Abstract

A power management system (12) in an electronic device (10). The system comprises circuitry (14 x ), responsive to at least one system parameter, for providing data processing functionality, where the circuitry for providing data processing functionality comprises a data path(CP x ). The system alternatively or cumulatively also comprises circuitry (22 x ) for indicating a potential capability of operational speed of the data path and/or circuitry (24 x ) for indicating an amount of current leakage of the circuitry for providing data processing functionality. The system also comprises circuitry (26) for adjusting the at least one system parameter in response to either or both of the circuitry for indicating a potential capability and the circuitry for indicating an amount of current leakage.
